Of the reflector that reflects light from a straight tube-shaped lamp diagonally downward toward the wall , the lower end of the portion facing the wall is bent upward, and the reflecting surface of the bent portion is used to reflect light from other portions of the reflector. 1. A wall illumination fixture characterized by reflecting the light in a near-horizontal direction and increasing the diffusivity of the reflective surface of the bent portion compared to other portions of the reflector .

Claims

[Scope of utility model registration request]

In a wall lighting fixture that is embedded in the ceiling, the light from the lamp is reflected toward the wall in a direction perpendicular to the longitudinal direction of the straight tube-shaped lamp, which is placed so that its longitudinal direction is parallel to the wall to be illuminated. It has a reflector, and the lower end of the reflector facing the wall is bent so that the lower end of the reflector illuminates the upper part of the wall, and there is no part where the illuminance drops sharply in the vertical illuminance distribution. A lighting fixture for wall illumination, characterized in that the diffusivity of the reflective surface at the bent portion is higher than that of other reflective surfaces so that a decrease in illuminance at the upper part of the wall surface is small.
